The determination of the motor and battery specification is one of the major challenges in the electric vehicle designs, specially considering the different kinds of requirements and specifications in different designs. This paper discusses about a method of simulating a vehicle in given terrains and driver models for extracting the torque, power and battery usage; and hence get the most optimized set of parameters for the given design requirement. The simulation takes the driver as a fuzzy model and the overall vehicle as a non-linear model for calculating the motor and battery requirements according to the terrain, driver commands and traffic condition.

The increase in security concerns on issues such as identity, theft indicates the needs of a new reliable security system. Iris recognition is perhaps the most accurate means of personnel identification due to the uniqueness of the patterns contained in each iris. This paper presents new image processing algorithm which specifically focuses on the characteristics of the phase components obtained from two-dimensional Fourier Transformation of image. The Phase Only Correlatlon (POC) and Band Limited Phase Only Correlatlon (BLPOC) are the most fundamental transformations, the features of which include superior discrimination capability over the ordinary recognition system.

The error probability of DPSK signals in Nakagami fading with EGC diversity reception is analyzed. The error rate is expressed as a (L + 1)-fold integral that contains only simple mathematical functions for L channel reception. The multiple integrals are easily evaluated with the Gauss-Legendre quadrature. Numerical values for the error rates of binary, quaternary and octonary DPSK signals are presented for several fading severity levels.

Traceability systems have become a dominant management information system within the production and marketing companies as they can efficiently control the supply chain, by minimizing the risks of the production process, and helping to enhance the consumer/customer reliability on products. There may have some limitations of using available traceability systems with small and medium scale industries as there may have design-reality gap of such systems.

The study of empirical propagation models for mobile channels has been done extensively, but the applicability of those models to a Fixed Wireless Access (FWA) System is not appropriately tested. The candidate models include Hata - Okumura, COST 231 Hata, COST-Walfisch-Ikegami and Erceg. From those models Erceg model seems to be the most suitable. In this paper field measurements are taken for the 3.5GHz Fixed WiMAX network in Katubedda, Sri Lanka. Those are used to validate the applicability of the above mentioned propagation models in a sub urban environment in Sri Lanka.

The Axial Flux BLDC motors are relatively new, specially at higher power ratings over 10kW. Therefore the designers face a lot of difficulties in designing and optimizing the motor for a given application. This paper presents a new method to optimize the performance in speed, torque, torque stability, power output, power density and motor dimensions in view of the cost and reliability for a given motor; specially to be used for traction purposes. By this method, the motor designers can easily choose the exact parameters of the motor to match the requirement and make sure of the optimization of the design. A software interface and simulation results are presented to check the level of optimization achievable with the system. This paper discusses a three phase axial flux outer rotor BLDC motor, but the core equations can be easily changed to simulate for any kind of motor with the same software and simulation interface.

In this paper, the proposed interconnection of Sri Lankan power system grid and southern regional grid of Indian grid is modeled using a simple VSC configurations based on HVDC transmission. The control implemented is made in such a way that this will allow power transmissions in either way. Therefore voltage vector PLL based control together with DC-link voltage regulation is implemented. Here the HVDC both end VSC are operated with very similar controls and the only difference is one is operated as main and the other operated as sub. The main VSC controls the power flow and other follow up the main. The proposed system is modeled using PSCAD/EMTDC. Whilst the Impact of frequency variation and sudden load rejection due to one of the grid system failure is being analyzed in this paper, the reactive power control at both ends VSC to support the voltage regulation is also being studied. Simulation results show as to how the transients due to frequency fluctuation and country blackout will impact the HVDC transmission line's operations.

Many equipment manufactures introduce proprietary protocols in network monitoring and equipment configuration to maintain market monopoly. This paper presenting a low cost solution to access, monitor and configure such equipments irrespective of its communication method. The solution consists of especially designed hardware modules which are collocated and connected with the equipments (need to monitor remotely) distributed over large geographical area. The system is designed such that multiple peer to peer connections can be setup with remotely held equipments to ensure the physical connectivity. Due to its' peer to peer and low level nature, system supports proprietary or standard network monitoring despite the differences of the equipment or the network monitoring software implementation. Furthermore, this paper discuss the solution facilitated the transportation of analogue and digital alarms from remote sites to a central network monitoring node which often equipment operators need separate transport system.

Due to more overhead of asymmetric cryptosystems, traditionally, the symmetric cryptosystem is used to encrypt long messages. In case of symmetric cryptosystems, it creates the problem of key management. So to encrypt long messages, we usually, take the help of both symmetric and asymmetric cryptosystems. In this paper, we proposed an asymmetric cryptosystem for encrypting long messages, which is not only efficient but also secure. In consideration of the aspect of efficiency and computation, our proposed scheme uses elliptic curve cryptosystem.

In this paper, a simple and efficient power split rule based energy management algorithm is designed for optimal sharing of energy between different energy sources in parallel HEV. This algorithm is simulated in MATLAB for Indian driving cycle (urban drive cycle) and Indian express highway drive cycle. The results indicate that the split of power can allow the engine to operate at its best efficiency and the life of battery can also be improved significantly with the introduction of ultracapacitor by maintaining the battery state of charge (SOC) within desired limits.
